Acute myocardial infarction and left bundle branch block.
نویسندگان
چکیده
Complete left bundle branch block often masks old as well as acute myocardial infarctions. However, a diagnosis of acute myocardial infarction in the presence of complete left bundle branch block can be made when the acute injury current is large enough to modify the secondary repolarization abnormalities of left bundle branch block. Under these circumstances the classical ST-T changes of an acute infarction may evolve in serial electrocardiograms.

متن کاملAcute Myocardial Infarction with Bundle Branch Block (Rbbb or Lbbb) - Clinical Characteristics, Complications & Prognostic Significance - A Hospital Based Study
The occurrence of bundle branch block in acute myocardial infarction is important because it indicates that infarction may be extensive and may result in cardiac failure or death; however, the presence of bundle branch block is also important because it indicates seriously jeopardized AV conduction which could result in sudden extremely slow heart rates or asystolic arrest. The aim of the study...
متن کاملAcute myocardial infarction in the presence of left bundle branch block.
Background. The presence of left bundlebranch block on the electrocardiogram may conceal the changes of acute myocardial infarction, which can delay both its recognition and treatment. We tested electrocardiographic criteria for the diagnosis of acute infarction in the presence of left bundle-branch block. Methods. The base-line electrocardiograms of patients enrolled in the GUSTO-1 (Global Uti...
متن کاملElectrocardiographic signs of acute myocardial infarction in left bundle branch block.
INTRODUCTION Acute myocardial infarction is characterized by typical chest pain, electrocardiographic changes in terms of lesion and/or myocardial ischemia and increased cardiac enzymes. It is often difficult to make diagnosis in the presence of non-specific chest pain, the short duration of symptoms and electrocardiographic signs of a complete left bundle branch block. LITERATURE REVIEW Many...
